T0 cZZ whom it may concern."

Be itknown that 1, DAVID J. NYSEWANDER, a citizen of the United States, and a resident of- Toledo, in the county of Lucas and State of Ohio, have invented a certain new and usefulLiquid-Fuel'Burner; and I do hereby declare the following to be a full, clear, and ma description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference beingha'd to the accompanying drawing, and to the characters of reference marked thereon, which form a part of this specification.

My invention particularly has for its ob ject to provide, in conjunction with a liquid fuel burner, a chamber which will produce a uniform pressure of the gas which is generated by the heat of the burner. The chamber is connected intermediate the point of generation of the gas from the liquid and the burner which generates the gas. The invention also has for its object also to provide, in conjunction with such a chamber, a plurality of burners which burn the gas generated by one of the burners, the burners being connected to the source of fuel supply and the auxiliary or pressure controlling chamber being connected intermediate the gas generating chamber and the other burners which consume the gas generated.

The invention may be used in different constructions for the regulation of the pressure of gas generated from a liquid fuel and such constructions may be used for different purposes where heat is required. For purposes of illustration I have selected one of the constructions containing my invention and shall describe it hereinafter. The construction selected is illustrated in the drawing.

Figure 1 of the drawings is a side view of a plurality of burners containing my invention. Fig. 2 is a top view of the burners shown in Fig. 1. Figs. 3 and a are sections taken on lines 33 and l lindicated in Figs. 1 and 2.

1, Fig. 1, is the generator burner. it is connected to a casting 2 having a flange 3, which forms a shallow receptacle for receiving the oil which may be allowed to flow from the burner 1 preparatory to starting the burner, that is, for priming purposes. A cylindrical disk shaped hollow member having a generating chamber is Specification of Letters Patent.

connected through a pipe 4- with the burner 1 and through the pipe 5 with asource of liquid fuel supply. The casting 6 is prefer ably dislnshaped forming a short hollow cylindrical member into which the liquid fuel flows from the pipe 5. The heat of the priming iiuid soon generates a gas in the cylindrical or disk-shaped member6 and the gas passes down through the piped and out through the burner 1. It is ignited by the burning fuel allowed to collect in the shallow pan or saucer 2. The member 6 being cylindrical in form, causes the flame to spread radially and not only generate gas in the member 6. but also permits heat to be supplied to any article that may be located above the member 6. A pipe 7 connects a hollow member 8 forming a closed.

chamber intermediate the burner 1 and the cylindrical member 6 in which the gas is generated. The upper end of the member 8 is closed, and thus forms a pressure chamber. The gas in the chamber 8 forms a cushion which keeps a constant pressure at the burner 1. The fuel entering the cylindrical member 6 is changed into gas and produces a changing pressure in the pipe 5, which acts as a back pressure on the supply of the fuel, but as the fuel flows irregularly, that is, as the gas is allowed to escape, the fuel moves toward the cylindrical member 6, and as this forward movement is variable, there is a tendency to produce a constantly varying amount of the gas in the member 6 which again results in the production of a variable pressure in the pipe 5. This varyin pressure occurring in the member 6 is communicated through the pipes 4 and 7 to the chamber of the hollow-member 8, which counteracts the effect of the varying pressure in the member 6 and causes a substan tially constant pressure in the ,burner 1 which will produce a substantially constant temperature and thus in turn reduce the variable pressure that tends to occur in the member 6.

l f desired, burners, such as the burners 9, may be connected with the burner 1 and the members 6 and 8 by means of the pipe 10. A valve 11 may be located in the pipe 10 and may be suitably placed with reference to the device, such as a stove, containing the burners, in order that the supply of the gas to the burners 9 from the point of generation may be controlled. The pressurechamber being connected intermediate the point of generation and the burners 1 and 9, pro duces a uniformpressure in all the burners.

A supply offuel to the burners may be controlled by the valve 12. It is connected to the pipe 13, Which is in turn connected to the source of fuel supply.

The short cylindrical member 6 is preferably provided with a core 30 so as to form an annular chamber 31. The member 6 is so placed that the center of the core 30 Will be directly over the outlet or center of the burner 1. The jet thus strikes the member 6 directly below the center of the core and is deflected radially. This prevents the fuel from being charred by the intense local heat that is produced directly over the outlet of the gas.

I claim:

In a liquid fuel heater, a member having an annular chamber and a solid core portion, the chamber being connectedwith the source of fuel supply, a burner so located below the member to cause the flame of the burner to impinge on the solid core portion and connected With the outlet of the chamber of the said member for heating the fuel supply to the said member, a plurality of burners connected at a point intermediate the first named burner and the said member, a short gas pipe closed at one end connected intermediate the first named burner and the chamber and intermediate the chamber and the last named burner and forming a closed chamber communicating with the pipe interconnecting the first named burner and the said member With the last named burners. y

In testimony whereof, I have hereunto signed my name to this specification.

DAVID J. NYSEVVANDER.
